Gas expansi onslciihlvorr i ch tungGas expansion valve
Die Erfindung betrifft eine klein bemessene Gasexpansionskühlvorrichtung. The invention relates to a small-sized gas expansion refrigerator.
Es sind bereits einfache Expansionskühler des Joule-Thompson Typs bekannt, die einen Wärme-Austauscher Λ enthalten, der durch ein dünnes Rohr gebildet wird, " das mit schraubenlinienförmig um einen Dorn gewickelten Rippen versehen ist. Der Wärme-Austauscher endet in einer kleinen zur Expansion dienenden Öffnung und das Ganze ist mit fester Reibung im Innern eines Rohres angebracht, das durch Vakuum thermisch isoliert ist. Im Innern des Rohres steigt das durch die Expansion gekühlte Gas in Gegenströmung längs des dünnen Rohres, das das noch nicht expandierte Gas abkühlt; dieser Vorgang ist kumulativ und ermöglicht, das Gas nach gewisser Zeit flüssig zu machen.Simple expansion coolers of the Joule-Thompson type are already known which contain a heat exchanger Λ which is formed by a thin tube "which is provided with fins wound helically around a mandrel. The heat exchanger ends in a small one for expansion The whole is attached with firm friction inside a tube which is thermally insulated by vacuum.In the inside of the tube the gas cooled by the expansion rises in countercurrent along the thin tube, which cools the not yet expanded gas; this process is cumulative and enables the gas to become liquid after a certain period of time.
Es sind auch Groß-Anlagen zum Flüssigmachen oder zum |There are also large systems for making liquid or for |
Kühlen bekannt für wissenschaftliche Zwecke oder für großindustrielle Zwecke, wobei die Kühlung in zwei Stufen erfolgt, wobei die erste Stufe als Vorkühlung für die zweite dient.Cooling known for scientific purposes or for large-scale industrial purposes, cooling in two Stages takes place, with the first stage serving as pre-cooling for the second.
Diese Anlagen sind teuer und groß bemessen und die Anwendung kommt nur in Spezialfallen in Frage.These systems are expensive and large in size and use is only possible in special cases.

Die Vorrichtung nach der Erfindung ist dadurch gekennzeichnet, daß sie in einem einzigen thermisch hochisolierten Rohr zwei Elemente enthält, die je einen Wärme-Austauscher besitzen, dem eine Expansionsvorrichtung folgt, welche Elemente in parallel durch das zu kühlende Gas gespeist werden und nebeneinander in thermischer Berührung in diesem Rohr angeordnet sind, so daß das erste Element als Vorkühler für das zweite, am Boden des Rohres angebrachte Element dient. Es zeigt sich, daß der Wirkungsgrad dieser Vorrichtung erheblich höher ist als der der zwei, thermisch parallel gelegten Elemente .The device according to the invention is characterized in that it is highly thermally insulated in a single one Tube contains two elements, each of which has a heat exchanger, which is an expansion device follows which elements are fed in parallel by the gas to be cooled and next to each other in thermal Contact are arranged in this tube, so that the first element as a pre-cooler for the second, on the ground The element attached to the pipe is used. It turns out that the efficiency of this device is considerably higher is than that of the two thermally parallel elements.
Die Erfindung wird anhand beiliegender Zeichnung näher erläutert, in derThe invention is explained in more detail with reference to the accompanying drawing, in which

in Fig. 3 schematisch dargestellt, da es für die Erfindung unwesentlich ist. Deutlichkeitshalber ist der Durchmesser in vergrößertem Maßstab angegeben. In jedem dieser Elemente wird der Gegenströmungsaustauscher durch ein Nickelrohr 1 (in vergrößertem Maßstab in Fig. 2 dargestellt) gebildet, auf welches ein Silberdraht quadratischen Querschnittes 2 zur Bildung der Rippen gewickelt ist. Das so gebildete Rohr wird an sich auf den durch ein thermisch isolierendes Element gebildeten Dorn z.B. aus Nylon gewickelt, der durch zwei aufeinander folgende Teile 50 (Element A) und 51 (Element B) gebildet wird, die durch eine Silberbuchse 52 miteinander verbunden sind. Das zu verflüssigende Gas (Stickstoff oder Argon) wird unter hohem Druck (150 bis 200 Bar) durch ein Endstück 3 zugeführt, das im Schnitt in Fig. 1 dargestellt ist und das ein poröses Kupferfilter 4 enthält. Von diesem Endstück her stehen zwei Rohre 5 und 6 vor; das Rohr 6 ist mit der Expansionsvorrichtung 8 verbunden, die durch eine Kammer gebildet wird, die mit der Umgebung durch eine Öffnung einiger Hundertstel Millimeter in Durchmesser in Verbindung steht, welche Öffnung entsprechend der erwünschten Leistung veränderlich ist. Das Gas entweicht durch zwei kleine Öffnungen 9 der Buchse 52, während es abkühlt und kehrt längs der Rohre' 5 und 6 zurück. Die Expansions- ^ vorrichtung 8 liefert auf diese Weise eine Vorkühlung. An dieser Stelle häuft sich an der Buchse 52 der flüssige Stickstoff an. Das Rohr 5 aus Nickel, das nicht mit Rippen versehen ist, wird um das Rohr 6 und die Buchse 52 gewickelt und speist das zweite Element B. Letzteres ist ähnlich dem ersten Element aufgebaut mit einem gewickelten Austauscher mit dem Draht 5, der bei 5' Rippen bildet wie der Draht 6 des Elementes A. Es enthält eine Expansionsvorrichtung 14» die in Fig. 1 in drei Teile zerlegt dargestellt ist. Ein mit Gewinde versehenes Endstück 10, an dessen Ende eine Scheibe 11 angebracht ist,shown schematically in Fig. 3, since it is not essential to the invention. For the sake of clarity, that is Diameter indicated on an enlarged scale. In each of these elements there is a counterflow exchanger formed by a nickel tube 1 (shown on an enlarged scale in Fig. 2) on which a silver wire square cross-section 2 is wound to form the ribs. The tube thus formed will turn on wound on the mandrel formed by a thermally insulating element, e.g. made of nylon, which passes through two successive parts 50 (element A) and 51 (element B) is formed by a silver bushing 52 are connected to each other. The gas to be liquefied (nitrogen or argon) is under high Pressure (150 to 200 bar) supplied through an end piece 3, which is shown in section in Fig. 1 and which is a porous copper filter 4 contains. Two tubes 5 and 6 protrude from this end piece; the tube 6 is with the Expansion device 8 connected, which is formed by a chamber which is connected to the environment through an opening a few hundredths of a millimeter in diameter communicates which opening corresponds to the desired Performance is changeable. The gas escapes through two small openings 9 of the socket 52 while it cools and returns along tubes 5 and 6. The expansion device 8 provides precooling in this way. At this point, the liquid nitrogen accumulates on the socket 52. The tube 5 made of nickel, which is not ribbed is provided, is wound around the tube 6 and the sleeve 52 and feeds the second element B. The latter is constructed similar to the first element with a wound exchanger with the wire 5, which forms ribs at 5 ' like the wire 6 of element A. It contains an expansion device 14, which in FIG. 1 is divided into three parts is shown. A threaded end piece 10, at the end of which a washer 11 is attached,
909882/0606909882/0606
die eine Expansionsöffnung hat, und eine Passung 12 sind vorgesehen, die auf das Endstück 10 geschraubt sind und zum Befestigen des Ganzen dient. Der Austauscher 5 endet in dem Endstück 10 und das Gas expandiert durch die Öffnung der Scheibe 11. Das Gas strömt darauf längs des Rohres 5' (Element B) und darauf längs der Rohre 5 und 6 (Element A) zurück. Der flüssige Stickstoff häuft sich am Boden eines Rohres 7 an, an welches z.B. ein Kühlring (nicht dargestellt) eines Mosaikinfrarotanalysators angeschlossen werden kann, dessen Verbindungen auf sehr niedrige Temperaturen abgekühlt werden sollen. Diese Anwendung ist selbstverständlich nicht exklusiv. Die Vorrichtung nach der Erfindung kann in allen Fällen verwendet werden, in denen die Aufgaben der Abmessungen, der Handhabung und des niedrigen Gestehungspreises wichtig sind.which has an expansion opening, and a fit 12 are provided, which are screwed onto the end piece 10 and used to fasten the whole. The exchanger 5 ends in the end piece 10 and the gas expands through the opening of the disc 11. The gas then flows along the tube 5 '(element B) and then back along the tubes 5 and 6 (element A). The liquid nitrogen piles up at the bottom of a pipe 7 to which, for example, a cooling ring (not shown) of a mosaic infrared analyzer is connected whose connections are to be cooled to very low temperatures. This application is of course not exclusive. The device according to the invention can be used in all cases in which the tasks of the dimensions, the handling and the low cost price are important are.
Die erwähnten Gase sind nicht die einzigen, die hier anwendbar sind. Das Rohr 6 kann z.B. durch Stickstoff und das Rohr 5 mit Wasserstoff gespeist werden, wobei letzterer verflüssigt werden soll.The gases mentioned are not the only ones that are applicable here. The pipe 6 can e.g. the pipe 5 are fed with hydrogen, the latter to be liquefied.
Die Bedeutung der kleinen Bemessung ist besonders ausgeprägt, wenn man bedenkt, daß es möglich ist, auf diesem Prinzip Verflüssiger mit einem Durchmesser von 5 mm und einer Länge von einigen Zehn cm anzuwenden. Die Abmessungen der Vorrichtungen hängen selbstverständlich von der Kühlleistung ab und bei den erwähnten Werten ist die Leistung etwa 5bis 10 W.The importance of the small dimensioning is particularly pronounced when you consider that it is possible on this Principle to use condensers with a diameter of 5 mm and a length of a few tens of cm. The dimensions of the devices depend of course on the cooling capacity and with the values mentioned, the Power about 5 to 10 W.
Die Vorrichtung nach der Erfindung läßt sich weiterhin bequem anpassen. Die Expansionsvorrichtungen 8 und 14 sind auf gleiche Weise aufgebaut, so daß je nach den verwendeten Gasen und den erwünschten Leistungen der Durchmesser der Öffnungen in den Scheiben 11 geändert werden kann. Es genügt, die Scheibe 12 zu entfernen und durch eineThe device according to the invention can also be easily adapted. The expansion devices 8 and 14 are constructed in the same way, so that depending on the used Gases and the desired performances the diameter of the openings in the disks 11 can be changed. It is sufficient to remove the disc 12 and through a
909882/0606 " 5 909882/0606 " 5
andere mit einer Öffnung geeigneten Durchmessers zu ersetzen. Bei der Expansionsvorrichtung 8 ist es dann notwendig, den Teil des Doms 50 von der Buchse 52 zu entfernen, was unbedenklich ist, da die durch die Windungen des Drahtes 5 um diese Buchse gebildete Feder eine hinreichende Elastizität hat.to replace others with an opening of suitable diameter. In the case of the expansion device 8 it is then necessary to remove the part of the dome 50 from the socket 52, which is harmless, since the windings of the wire 5 formed around this socket spring has sufficient elasticity.
